Última Approche comparative de la variabilité et de la structuration génétique chez deux espèces d'huîtres cultivées (Crassostrea gigas et Ostrea edulis) présentant des stratégies reproductives et des histoires contrastées ArchiMer Boudry, Pierre; Launey, Sophie; Huvet, Arnaud. The two common oyster species cultivated in Europe are the flat oyster Ostrea edulis and the cupped oyster Crassostrea gigas. These species have two really different reproduction strategies (oviparity versus larviparity) and histories (natural distribution versus introductions linked to oyster culture). We used microsatellite markers to compare the observed variabilities Europe wide. O. edulis presents a lower rate of alleles per locus than C. gigas. The observed structuration levels (global Fst and by pairs values) are similar for both species, but the spatial organisation of the diversity is different. In O. edulis, appears a differentiation based on the distance (concordance of the results with those obtained with the allozymes) whereas in C. gigas,...

Ano: 1986 URL: http://archimer.ifremer.fr/doc/00110/22125/19761.pdf Interactions basses fréquences océan-atmosphère dans l’océan Austral ArchiMer Maze, Guillaume. Patterns of interannual variability of the ocean- atmosphere coupled system in the Southern Hemisphere ex- tratropics are studied with a simple dynamical model, in or- der to determine the basic physical processes of interaction independently of tropical forcing. The model used is an at- mospheric quasi-geostrophic model coupled to a "slab" oceanic mixed layer, which includes mean geostrophic advection by the Antarctic Circumpolar Current (ACC). The ocean-atmosphere coupling occurs through surface heat fluxes and Ekman cur- rent heat advection. In a fully coupled simulation, the atmos- pheric part of the model, which includes high frequency tran- sient eddies at midlatitudes, exhibits a strong Southern Annu- lar Mode (SAM) as the first mode of variability...

The causality of recruitment is of paramount importance for the progress of the control of marine living resources, but its study remains technically complax.The aim of the Nantes panel was to evaluate the state of advancement of three running programs on exploited species (sole, scallops and oysters), and to set out the basis of a wider national program of interest for both basic and targeted research.

ArchiMer Boudry, Pierre. Despite the economic importance of oyster farming, knowledge about genetic resources of these species is still limited. The objectives of my research were to provide further information about (1) taxomomy, phylogeny and phylogeography of Crassostrea oysters, (2) to compare C. gigas and C. angulata strains of various geographic origins and (3) to study phenotypic and genetic variation for traits of aquacultural interest in C. gigas. Studies based on DNA polymorphism and chromosomes allowed to improve or correct identification, geographic range and phylogeographic relationships among several species. The comparison of various strains of C. gigas and C. angulata, both in laboratory and field conditions, revealed significant differences among taxa and the...

Ano: 2003 URL: http://archimer.ifremer.fr/doc/2003/these-3354.pdf Typology of individual growth in sea bass (Dicentrarchus labrax) ArchiMer Gardeur, J; Lemarie, Gilles; Coves, Denis; Boujard, Thierry. The individual growth variability of passive integrated transponder tagged sea bass was studied using data sets from two different experiments. In experiment 1 (n = 485), fish submitted to different photoperiod regimes were held in fourteen groups of individual weight of 88 ± 13 g (mean ± SD). In experiment 2 (n = 748, initial weight 243 ± 30 g) fish were held in fifteen groups and had either free or restricted access to diets with three lipid levels. After adjustment for treatment and tank effects, individual growth curves were analysed using multivariate analysis (principal component analysis and clustering) and were modelled using the summary statistics technique. Different growth profiles where characterized. All of them appeared to be curvilinear....

Traceurs géochimiques (Eléments nutritifs et fréons) ArchiMer Morin, Pascal; Louarn, Essylt; Thoumelin, Guy; Sevin, Laure; Cariou, Thierry; Mace, Eric. Le nord de l'Atlantique Nord est le lieu de formation de l'eau profonde Nord Atlantique, composante essentielle de la circulation thermohaline. Le travail faisant l'objet du présent contrat avait pour objet de réaliser des mesures de composants biogéochimiques des masses d'eau le long d'une radiale allant du Groenland au Portugal en 2008 (section OVIDE). Les différentes composantes constituant l'eau profonde Nord Atlantique ont été échantillonnées. Ces mesures complètent des observations déjà effectuées par la même équipe en 2002,2004 et 2006. La mise en perspective temporelle de l'ensemble de ces données donne des informations sur la variabilité des masses d'eau océanique et par extension de la circulation.

Ano: 2012 URL: https://archimer.ifremer.fr/doc/00329/44006/43578.pdf Etude de la variabilité de la circulation du gyre subpolaire de l'Atlantique Nord à partir des données Ovide et de mesures satellitaires ArchiMer Gourcuff, Claire. The cyclonic circulation of the North Atlantic subpolar gyre, between 50°N and 63°N, plays a key role in the climate variability. The Ovide program contributes to the observation of the circulation in this region. A section is repeated every two years in summer since 2002 between Greenland and Portugal following a path close the Fourex 1997 section. To get transport estimates across the sections, a geostrophic box inverse model is used, constrained with direct current measurements. Our new estimates of Fourex transports show the need to use constraints temporally associated with the section to get transports estimates representative of the circulation at the section realisation dates. It is also shown that altimetry velocities can be used instead of ADCP...
